Akron’s sinkhole can be explained.

The gaping hole on Kling Street near the intersection of Rankin Street was caused by another hole: in a 24-inch sanitary sewer line. The dirt under the road slowly had been sinking into the sewer line, Public Service Director John Moore said Thursday.

“It has been undermining the street for a significant amount of time,” he said. “It was lucky the road was real thick.”

The city has contracted with Kenmore Construction Co. of Akron to fix both the sewer pipe and the road. The company will be on the site this morning, and the project is expected to be finished by Monday or Tuesday, Moore said.

“Unless they run into another issue,” he added.

Kling Street is expected to remain blocked off until the work is done.

The city learned about the hole, which is about 20 feet long, 15 feet wide and 12 feet deep, when a resident called the 311 information line about 4 p.m. Wednesday. A motorist driving on Kling stopped when he saw the hole and alerted a resident on the street.

Daniel Hall, the resident, told the Beacon Journal on Wednesday that he walked over and the hole “started spreading and pieces of concrete kept falling and it started caving in even more. It’s kind of scary.”

No one was injured by the hole, with city officials quickly roping off the area and blocking the street. Moore said he is glad the hole didn’t open up at night when it would have been harder for a motorist to spot.
